The origins of Artificial Intelligence (AI) usually begin with the theories proclaimed by ancient Greek philosophers and scientists. Although, arguments can be made that the first attempts were made thousands of years before, at the dawn of humanity. Long before the invention of writing, humans appear to have developed rudimentary techniques and tools for counting and representing information.

I’m proud to announce a new version of the EVA (Evolutionary Virtual Agent) implemented using Javascript and JQuery. The core is 100% Javascript. It is a simpler version compared to the regular one implemented in C and running on both Windows and Linux. However, this implementation enables the design of most intelligent conversational characters without any strong limitation. It’s simple to

Il faut bien reconnaître que, le plus souvent, ce sont les capacités des technologies employées qui font l’objet des principales attentions lorsque l’on crée un agent intelligent ou, plus généralement, un personnage artificiel. Parmi les questions récurrentes : Est-ce que l’IA se limite au syntaxique (recherche de mots clés, etc.) ou bien sémantique (analyse du sens, ontologie, etc.), est-ce un «

Voici un ouvrage très recommandable! D’une part c’est un livre de grande qualité qui a le mérite d’aborder la question cruciale du « post-humain », avec ses inévitables débats éthiques, prophétiques, polémiques, etc., tout en restant accessible au plus grand nombre. D’autre part, autant le dire tout de suite, j’ai été très honoré de figurer parmi les personnalités interrogées où figurent quand

Les experts militaires évoquent une véritable "révolution". La robotisation du champ de bataille s'accélère. La technologie est mûre pour bouleverser la guerre : car la perspective, désormais à portée, est celle d'une automatisation de l'usage de la force, de l'acte de tuer. Seraient balayées les lois de l'écrivain Isaac Asimov exigeant qu'un robot ne puisse porter atteinte à un être humain et

Alors que les commentateurs s’interrogent sur la survie d’Apple après le décès de Steve Jobs, la firme à la pomme propose a priori une « simple » évolution de l’Iphone 4. Nombreux ont été déçus par cette annonce en demi-teinte alors qu’ils s’attendaient à un iPhone 5 débordant de nouveautés, en hommage au départ sans retour possible de leur gourou.

In 1950, Alan Turing proposed a general procedure to test the intelligence of an agent known as the Turing test (TT). The idea was to talk in natural language using a computer screen and a keyboard to one machine and one human. All participants are separated from one another and cannot see the other ones. After an arbitrary amount of time, if the “judge” cannot reliably make a difference between

I want to make a short comment about “The Media Equation” from Reeves and Nass* since it has many implications for the design of artificial creatures.Their theory claims that humans are social animals that come from their evolution history: they interact following the rules of interpersonal communication even if the interaction is not with a person (anthropomorphism). In other words, they tend to

Following my previous post on an extended version of Uncanny Valley applied to the study of complex systems, I want now to explain with more details my new approach to Artificial Intelligence. I've called this approach "Complex Artificial Intelligence".There have been numerous models of intelligence. The field of AI has been one of the most prolific since its birth in the middle 1950s.

L'université d’Osaka et les laboratoires ATR ont présenté un téléphone cellulaire original puisque celui-ci prend la forme d’une poupée humaine asexuée. Le premier prototype, baptisé Elfoid P1, est assez simple puisqu’il ne contient qu’une puce GSM basique et donc limitée à la communication par la voix uniquement. Plus intéressant est la « coque » du téléphone recouverte d’un gel de polyuréthane

HAL-9000 is an intelligent conversational agent developed for studying man machine interactions. The above screenshot shows the interactive graphical interface developped for this experiment. The graphical design was inspired by the motion picture movie 2001, A space odyssey directed by Stanley Kubrick (© Metro-Goldwin-Meyer 1968). This application was designed by a team of students at the IIM

Les éditeurs n'étaient pas présents au Festival du Jeu Vidéo cette année à la Porte de Versailles, mais cela n'a apparemment pas refroidi les visiteurs. En parlant de froid, sur le stand MSI, on pouvait admirer un impressionnant refroidisseur liquide pour une carte mère digne des meilleurs romans cyberpunk.

Sorry for that long delay but I was working on my new book, Robots & Avatars. Here is a "teaser":Since the dawn of humanity, man tries to replicate the living. Among the legends that have influenced this quest, the myth of Pygmalion has a special place. Helped by Venus in the genesis of an artificial beauty, the ancient king fell to his irresistible charm. Since then, the descendants of Galatea

EVA is developped as an open source project. The major part of the source code is designed with the NanoScheme Language and requires no compiler nor specific developement tools. However, we encourage the use of a text editor with Lips editing capabilities such as Notepad++.

Gabriel Casbai and his team of IIM students have developed for EVA an "avatar factory". This prototype is designed using (Adobe) Flash and implements an interactive Genetic Algorithm. The principle is quite simple. The tool creates a population of avatars with different eyes, noses, hairs, etc. The user can then select some of these characters and the tool applies crossing-over and mutation

In January this year, I have published the book “Les Créatures Artificielles” (Odile Jacob, Paris). It covers the history, trends and perspectives of Artificial Creatures. I have written these 500 pages as a reference book covering both scientific and cultural aspects of this fascinating theme. From the erotic Galatee to the "Eve future", from the Golem to the Monster of Frankenstein, from the

The current EVA architecture is the result of the project evolution rather than a single design thread. The initial version of EVA was developed as an application running on the Windows desktop environment, with most features “hard coded” in C++. The creature design was limited to a simple 3D face (left part of the image), inspired by Ken Perlin’s face demo project. The second version (2004)

I began to work on EVA (Evolutionary Virtual Agent) in the year 2000 while I was experimenting with the LifeDrop virtual ecosystem. The initial idea was to design a virtual creature that was not a simulation like in most artificial life research projects. In other words, I wanted to realize an artificial life rather than to simulate life. The computer is not (only) a tool to simulate and explore,

Il faut dire, qu'entre temps, les projets et le développement de l'Institut ont bien pris mon temps... Mais bientôt tout ce travail se concrêtisera, entre autres, par l'ouverture d'une salle de démonstration multimédia. J'en reparlerai bientôt... En attendant, l'actualité est celle de la

Between the 15th and 22nd April, I was at the 6th International Workshop on Data Analysis in Astronomy «Livio Scarsi». The workshop was organized in Erice at the Ettore Majorana Foundation and Centre for Scientific Culture. The conference theme was quite large, Modelling and Simulation in Science, with contribution from three major branches: Astrophysics, Biology and Climatology. With my PhD

Finally, we have choosen a new 3D design approach for the LifeDrop virtual creatures. Each biomorph is composed of a set of 3D building blocks: segments, head, tail, antenna, eyes, etc. The DNA of a creature includes a structural template thatcan be evolved through mutation, cross-over and natural selection. The set of possible creatures is very big even if not really infinite. As in the previous

The third installation of our exhibition was based on our research about 3D Gravitational agents. The idea was to show some results of our simulations in 3D. We used two big LCD screens to display an introduction on emergent patterns at differents scales in the universe and the evolution of a globular cluster from a random distribution of matter.

This is an image of the second EVA installation we have made for the exhibition. This installation is based on the Evolutionary Virtual Agent technology for its Artificial Intelligence part. It basically enables the creature to interact with the user in natural language. In the near future, Eva will be also able to learn about the user and to search information on the web.

It has been a long time since my last post. We have worked a lot on a multimedia exhibition which takes place at the Leonard de Vinci University until the end of March (www.iim.fr/expo). In the next few posts, I will describe some of the installations we have designed with our students. The first one is an holographic artificial creature based on the EVA design (Evolutionary Virtual Agent).

Hello. Back to reality after some months of hard works on a book that will be published during next spring. More information later. In this post, I will rather focus on a new project we have begun with my friend Claude Lattaud of Paris V university. This project is called the "green tamagotchi project" after the great commercial success of Bandai's game. The idea is to take care of a plant on

As some of you may probably know, I am very interested in Biomorphs since the design of the Lifedrop virtual ecosystem (see the LifeDrop page on the right). In LifeDrop, the virtual water drop is like a 3D sphere with simple physical simulation. Biomorphs are true autonomous agents and their 3D shapes are based on the original Richard Dawkins recursive procedure simply called Tree in the Blind

In the recent years, there has been an increasing interest in simulating financial systems using multi-agent models and Cellular Automata (CA). There is a strong feeling that financial markets are typical complex systems in which the global dynamical properties mainly depend on the evolution of a large number of non-linear interacting agents. An extreme view of this is to consider that much of

This is the new 3D design for EVA (Evolutionary Virtual Agent). There are many improvements since the previous one (see last post on this subject). Now the student team is working on the screen setup and on the various face expressions: reference (no expression), happy, disapointed, annoyed, angry, etc. There are three main animation parts: left eye, right eye, and nose/mouth. Since all images

We have designed a hierarchical 3D multi-agent system for studying complexity at the cosmological level (see previous post on M31). Each agent is characterized by a set of properties: its position, velocity and mass, but also its diameter, density, viscosity, spin, etc. There are three simulation levels: (1) inside each agent (internal gravity that can lead to star formation, supernova, etc.), (2

Do you know that anyone on earth can be connected to any other person through a chain of acquaintances that has no more than five intermediaries ? (Six degrees of separation theory). Do you know that the size of a genuine social network is limited to about 150 ? (Dunbar Number).What is the network model of my organization ? What are the emerging patterns and dynamics ? Is my company well adapted

Here is the first 3D model for EVA (Evolutionary Virtual Agent) based on the preliminary drawings done in December (see previous post on EVA). This is a draft design since the model is not yet completed and there is no texture, no light, etc., but it gives a good idea of what will be the look of the final rendered face. All the 3D design is done by a student team of the IIM school (International

For Christmas, I bought the New Furby which was released in France at the end of the year. It is an advanced toy considering its technology and its relatively low price (near 50€ in France and less than 40$ in the US). The Furby looks like an armless Greemlins Mogwai with a beak. Evidence is that the New Furby cannot be considered as a living creature. However what is the opinion of my expert (

The Game of Life is certainly the most familiar Cellular Automata. It was introduced by John Conway in 1970 and popularized by the Scientific American journal. The Glider, a simple oscillating pattern that moves in the life universe, is generally presented as an emerging structure that gives an idea of what could be a minimal living creature. Is the Glider a useful modelof a living system ? The

This week I was invited to give a talk on the evolution of complexity at the "Faculté de Géographie et d'aménagement" (Louis Pasteur University) in Strasbourg (Thanks to Christiane Rolland-May and her team). It was also an opportunityto take a picture of its famous astronomical clock. The Strasbourg cathedral clock has a long history. The first clock was built in around 1352. It was replaced in

The weather was so cold in Paris that we decided to go in the south Tunisian desert for the last days of 2005 :)This travel gives me the opportunity to observe (and take pictures) many forms of complex natural landform patterns. Sand dunes represent a good example of rich emergent patterns produced by the nonlinear interactions between a very high number of simple agents : sand particules. Sand

We are now close to the end of this year. Another one. What was the most impressive image of complexity I have seen this year ? Probably this one. I take this picture at the top of the Tokyo City View tower last september. Imagine this at 250 meter above sea level offering 360-degree vistas of one of the most amazing city in the world: this is complexity. Happy christmas and happy new year

We have designed a 3D multi-agent system for cosmological simulations with the following original features. There are three basic types of interacting agents: star agents, gaz cloud agents and dark matter agents. Each agent as its own properties like mass, density, velocity, etc., but also spin and viscosity (!). We can then study the space of possible universes by modifying most physical laws

The earlier versions of the EVA project (Evolutionary Virtual Agent) were designed as C++ applications running under Windows. These versions included a simple real-time 3D engine for rendering the agent. The agent face 3D model used a small numbers of polygons (~100-500) focusing on a basic set of emotional expressions. This was inspired by the work done by Ken Perlin a few years ago with his "
